Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a compact container, and more specifically, a container body and a lid are hinged at their respective rear portions so that they can be opened and closed. A recess is formed in the front end edge of the recess, and a push piece is disposed within the recess so as to be movable in the front-rear direction, and a first engagement protrusion formed on the inner surface of the recess and a second engagement protrusion formed on the lid body are provided. The present invention relates to a compact container in which the lid body is closed by engagement with an engaging protrusion, and when the push piece is pressed inward in this closed position, a component force is generated to push up and open the lid body.

<Prior Art> Conventionally, this type of compact container has a push piece that is formed as a relatively hard piece of plastic, and an inclined surface that gradually descends from the top to the bottom rear is formed at the inner end of the plastic piece. The inclined surface is brought into contact with the lower end of the claw piece hanging down from the front end of the lid body, and when this push piece is pressed inward when the lid body is in the closed position, the vertical component of the inclined surface acts on the claw piece, causing the lid to close. A device in which the body is pushed up and released is known.

However, in this known compact container, the force acting on the claw of the lid from the inclined surface of the push piece is an oblique force perpendicular to the inclined surface, and this force causes the claw of the lid to move against the container body. This includes a component force in the horizontal direction that presses against the inner surface of the formed recess. This horizontal component force acts in the direction of strengthening the engagement between the first engaging protrusion formed on the inner surface of the recess and the second engaging protrusion formed on the claw piece of the lid body. Therefore, a relatively strong force was required to open the lid by pressing the push piece inward.

Therefore, as in the compact container shown in Utility Model Application Publication No. 60-44708, an actuating piece extending horizontally backward from the front wall for pressing is provided on the push piece that is slidably provided on the container body, and when the push piece is pressed, this As the tip of the actuating arm ascends the slope provided on the container body, the actuating arm tilts upward,
There is a known device in which the tip is pressed against the lower surface of the claw hanging from the lid and pushed upward.

However, in this known compact container, when the horizontally extended operating arm tilts upward, the claw piece is pushed upward, and although there is no rearward horizontal component force that presses the claw piece against the container side, the engagement The forward horizontal force that weakens the lid is small, and a relatively strong force is still required to open the lid.

<<Problems to be solved by the invention>> The invention of the present application was made in view of the above-mentioned problems, and its purpose is to prevent the force applied to the pushpiece piece from moving upward and downward when the pushpiece is pressed inward. To provide a compact container whose lid can be opened with a relatively small force by lifting it up while being biased forward.

<Means for Solving the Problems> In order to achieve the above object, according to the compact container of the present invention, a pressing front wall is provided in the recess formed in the front end of the container body, and A push piece having a bottom wall extending to the front wall is disposed so as to be movable in the front-rear direction, and the push piece is provided with an actuating arm extending obliquely from below the front wall to an upper rear part, and the front part of the actuating arm is attached to the front wall. The operating arm is pivoted at the lower rear position, and the front lower end of the operating arm is located at the connecting corner between the front wall and the bottom wall, and the rear upper end is brought into sharp contact with the inner surface of the recess, and the lid body is in the closed position. The upper end surface of the actuating arm is located close to the lower surface of the lid.

<<Embodiments>> Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 1 indicates a container body made of synthetic resin for storing cosmetics, etc., and a lid body 3 is hinged to the rear edge of the container body 1 via a pin 2 so as to be openable and closable. . A mirror 4 is glued to the inner surface of the lid body 3,
Further, a claw piece 5 is integrally formed to hang down from the front end edge. A recess 6 is formed in the front end of the container body 1 to correspond to the claw piece 5. This recess 6
A first engaging protrusion 7 is provided protruding above the rear surface of the holder, and a second engaging protrusion 8 is formed on the rear inner surface of the claw piece 5. When the lid body 3 is closed, the claw piece 5 engages with the container. Main body 1
When the second engaging protrusion 8 formed on the claw piece 5 passes over the first engaging protrusion 7 formed on the inner surface of the recess 6 and engages with the lid, the lid body assumes a closed position. become.

A stepped guide hole 9 is formed in the lower part of the inner surface of the recess 6 toward the inner part, and the lower part of the first engaging protrusion 7 on the inner surface forms a vertical wall surface 10.

In the present invention, a push piece 11 is disposed within the recess 6, and this push piece 11 is connected to a pressing front wall 12 formed approximately vertically.
It consists of a bottom wall 13 that extends horizontally from the lower end of the front wall 12 toward the rear, and side walls 14-14 that extend rearward from both ends of the front wall 12, and a lower inner surface of each side wall. is boss holder 15 and this boss holder 1
A tapered recess 16 is formed that gradually becomes wider from 5 toward the rear end surface of the side wall. An actuating arm 18 formed separately from the push piece 11 is disposed in the internal cavity, and bosses 19 are protruded from both sides of the front part of the actuating arm 18.
By fitting this boss 19 into the boss receiver 15 through the tapered recess 16, the operating arm 18 is rotatably pivoted to the side wall 14-14 of the push piece 11 at its front portion. The front end 20 of the actuating arm 18 is formed in a rounded arc shape, while the rear end has an inclined surface 21 formed on its upper surface.
Incidentally, reference numeral 17 is a hook-shaped projection provided on the lower surface of the bottom wall 13.

In order to assemble the push piece 11 configured as described above into the recess 6 of the container body 1, first attach the actuating arm 18 to the push piece 11 as described above, and then move the actuating arm 18 diagonally backward and upward. In the inclined state, the bottom wall 13 of the push piece 11 is pushed into the stepped guide hole 9 formed at the bottom of the inner surface of the recess 6. In this way, once the hook-like protrusion 17 on the lower surface of the bottom wall 13 is pushed over the lower step of the guide hole 9, the push piece 11 is assembled so as not to be pulled out from the guide hole 9.
In this way, when the push piece 11 is assembled into the recess 6, the front end 20 of the actuating arm 18 is attached to the front wall 1.
2 and the bottom wall 13, and its rear end slidably contacts the vertical wall surface 10 of the recess 6, and the angle formed by the lower surface of the operating arm 18 and the wall surface is an acute angle. become. In this state, the inclined surface 21 of the actuating arm 18 is almost horizontal and is located at the upper end of the actuating arm, and the claw piece 5 is in the closed position of the lid body 3.
